Function Synopsis

presents(eta)

Help text

PRESENTS Presents a parametric model on the screen.

   presents(TH)

   This function displays the model TH together with its standard
   deviations, loss function and Akaike's Final Prediction Error
   criterion (FPE).

   TH is defined in format for general state-space models, described
   by HELP TH.
